2016-05-09staging: unisys: visorhba: replace functionlike macro with functionAlexander Curtin
The `set_no_disk_inquiry_request` function now uses the correct min macro. Also I removed an unnecessary conditional. Get rid of u8 casts, u32 len, and u32 lun (which is actually defined as a u64 in the scsidev->lun field from whence it originated).

2016-05-09staging: lustre: o2iblnd: per NI map-on-demand valueAmir Shehata
Enables support of different map-on-demand values per NI. This is required to support OPA coexistence with MLX5 cards. MLX5 does not support FMR, which is enabled via map-on-demand. However OPA's performance is greatly enahanced when FMR is enabled. In order to enable coexistence of both of these two types of cards we need to be able to set different map-on-demand values for both NIs. This patch also lays the ground work for other per NI tunables to be added in future patches.

2016-05-09staging: lustre: fid: packing ost_idx in IDIFFan Yong
For a normal FID, we can know on which target the related object is allocated via querying FLDB; but it is not true for an IDIF. To locate the OST via the given IDIF, when the IDIF is generated, we pack the OST index in it. Then for any given FID, in spite of t is a normal FID or not, we has the method to know which target it belongs to. That is useful for LFSCK. For old IDIF, the OST index is not part of the IDIF, means that ifferent OSTs may have the same IDIFs, that may cause the IFID in LMA does not match the read FID. Under such case, we need to make some compatible check to avoid to trigger unexpected. tgt_validate_obdo() converts the ostid contained in the RPC body to fid and changes the "struct ost_id" union, then the users can access ost_id::oi_fid directly without call ostid_to_fid() again. It also contains some other fixing and cleanup.

2016-05-09usb: host: xhci-rcar: Avoid long wait in xhci_reset()Yoshihiro Shimoda
The firmware of R-Car USB 3.0 host controller will control the reset. So, if the xhci driver doesn't do firmware downloading (e.g. kernel configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR is not set), the reset of USB 3.0 host controller doesn't work correctly. Then, the host controller will cause long wait in xhci_reset() because the CMD_RESET bit of op_regs->command is not cleared for 10 seconds. So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM and CONFIG_USB_XHCI_RCAR.

2016-05-09iommu/dma: Implement scatterlist segment mergingRobin Murphy
Stop wasting IOVA space by over-aligning scatterlist segments for a theoretical worst-case segment boundary mask, and instead take the real limits into account to merge consecutive segments wherever appropriate, so our callers can benefit from getting back nicely simplified lists. This also represents the last piece of functionality wanted by users of the current arch/arm implementation, thus brings us a small step closer to converting that over to the common code.

nmk_gpio_get_mode is only used in one place, and that is conditionally compiled if DEBUG_FS is enabled. A recent cleanup has marked the definition 'static', which now leads to a warning: drivers/pinctrl/nomadik/pinctrl-nomadik.c:614:12: error: 'nmk_gpio_get_mode' defined but not used [-Werror=unused-function] static int nmk_gpio_get_mode(struct nmk_gpio_chip *nmk_chip, int offset) ^~~~~~~~~~~~~~~~~ Moving the function itself inside the #ifdef shuts it up again.

2016-05-09can: ifi: Update timing configuration codeMarek Vasut
The updated documentation regarding the IFI CANFD core from April 2016 adds more details regarding the timing calculation. There is no longer any distinction in the timing calculation between CANFD and CAN2.0, but instead there are two timing modes -- 4_12_6_6 and 7_9_8_8 -- where the numbers mean the width in bits of the SJW/Prescaler/TimeA/TimeB fields. The code uses 7_9_8_8 mode, which allows more fine-grained control over the timing.
